Hi! My name is David Ma.

I currently work on building and scaling LISA, a conversational real estate leasing AI, independently from 2017 and with the help of AppFolio since January 2019. I spend my time at the intersection of ML and product, trying to integrate them seamlessly.

Previously, I researched and implemented equity trading strategies at Two Sigma Investments between 2012 and 2017 after completing my bachelor's degree in mathematics at the University of Waterloo.

My hobbies come and go. Currently I photograph, ski, enjoy cooking (and eating), and follow the cryptocurrency space. In the past I've enjoyed go (weiqi), chess/bughouse, fencing, badminton, table tennis, rock climbing, classical piano, typography, SSBM, and probably a few other things.

My outdated resume, if you like that kind of stuff.
